When performing a battery drop test, make sure that the battery is dropped from the specified height to accurately assess its bounce behavior. The bounce of a battery during the test is influenced by various factors, including the alignment of molecules inside the battery.
Battery drop test is a crucial examination method to assess the durability and safety of batteries. In this test, batteries are subjected to simulated drops to mimic real-world scenarios. Understanding battery drop testing procedures, types, standards, and regulations is essential for ensuring product quality and compliance.
A voltage drop test can be easily applied in your production line, as opposed to often used complex systems that would also involve down-times for maintenance or additional calibration. When a battery has a defect such as a minute short-circuit, self-discharging causes the battery voltage to fall.
This testing can be a bottleneck in the manufacturing process, so test solutions that reduce time or increase test density are highly desirable. One of the most useful measurements for a battery cell or pack is the open circuit voltage (OCV), but the considerations that must be made at the module or pack level differ from the cell level.
If a slight drop in voltage is captured, it is possible to rapidly detect a defective cell. For tests like voltage drop tests for batteries where miniscule voltage changes are monitored over a long period of time to make a pass/fail judgment, the accuracy and long-term stability of the measuring instrument are essential.
If a battery fails the drop test, it must be analyzed to understand the failure mode. The design may need to be adjusted, materials changed, or additional protective measures to improve durability and safety. Can drop testing damage the battery permanently? Yes, drop testing can cause permanent damage to a battery.
